Thermal CAE Engineer - GM Defense

Description

The Role

Thermal CAE Engineer will be responsible for capturing information from a variety of sources inside and outside of GM Defense, building and running analytical models, interpreting results for customers, attending development team meetings, interacting with compartment integration teams and help to drive the design that meets internal and external requirements.

Thermal CAE Engineer will build, run, and interpret results from various thermal models ranging in complexity from a single component to complex full vehicle systems. The engineer will be an employee within a diverse group of engineers supporting the virtual analysis needs of GM Defense. The engineer will be interacting with the GM thermal analysis groups, performing airflow and thermal simulations of varying complexity. The engineer will drive the design of unique vehicles and systems intended for government applications using virtual analysis tools.

What You'll Do

Estimate propulsion heat rejection and determine air flow requirements for cooling system applications

Size cooling systems and determine cooling capacity required and air flow requirements for system condensers

Evaluate system exteriors with focus on cooling air flow and sealing using Computational Fluid Dynamics (CFD) models (front end cooling, passenger compartment)

Evaluate propulsion systems cooling and AC system performance using various simulations tools

Perform vehicle level CFD simulations to lead the design of the vehicle for thermal management

Develop and support novel approaches for analysis in controls, thermal integration, and controls co-sim development

Perform finite element and flow analysis on cooling system and plumbing components

Pro-actively develop simulations for new programs based on vehicle content and functional objectives

Post process and interpret simulation results to identify current performance gaps and develop solutions to improve performance

Daily use of several commercial CFD codes, solvers and supporting software in Windows, LINUX/UNIX and HPC environment. These include ANSA, STAR-CCM+, GT-Suites, MATLAB SIMULINK, and other Internal Codes.

Interface and collaborate with Studio and Engineering Teams, present numerical and visual data, and recommendations effectively, to ensure component and system level performance requirements are achieved

Fully engage in vehicle development activity and proactively take ownership of simulation activity to best guide the design team

Be willing to question the status quo and work to develop new methods and tools to streamline the defense toolkit in the thermal space
